NAME
       dgpthreadgroupequal - compare thread group IDs for equality

SYNOPSIS
       #include <pthread.h>

       int dgpthreadgroupequal(dgpthreadgroupt tg1,
                                  dgpthreadgroupt tg2);

   where:
       tg1    Thread group ID #1
       tg2    Thread group ID #2

DESCRIPTION
       This function compares the thread group IDs tg1 and tg2 for equality.
       In fact, this is the only supported way to compare two thread group
       IDs.

DIAGNOSTICS
   Returns
       The dgpthreadgroupequal() function returns a non-zero value if tg1
       and tg2 are equal; otherwise it returns zero.

       If either tg1 or tg2 is not a valid thread group ID, the behavior is
       undefined.  In the current DG/UX implementation, this case is
       impossible.

SEE ALSO
       dgpthreadgroupcreate(3T), dgpthreadgroupdestroy(3T),
       dgpthreadgroupself(3T), dgpthreadgroupgetlwpgroupid(3T).

NOTES
       The only other supported operations on thread group IDs are
       assignment and retrieval using a call to dgpthreadgroupself().

       Refer to dgpthreadgroupself(3T) NOTES for a more detailed
       discussion on proper use of thread group IDs.
